CrossOver Linux 9 (code-named Snow Mallard) and its Mac brother, CrossOver Mac 9, let you run many popular Windows applications on Linux or Mac OS X. Supported Windows applications include Microsoft Office (from Office 97 to Office 2007), Internet Explorer 6 and 7, Outlook 2002 to 2007, all current versions of Quicken up to 2010 and QuickBooks up to 2004, and some versions of Photoshop and Photoshop CS. Based on my experience with CrossOver, which goes back more than a decade, I’d say this new version supports about 20% more applications (at a level that most users would find usable) than the last one.
CrossOver is based on the open-source project Wine, an implementation of the Windows API on top of the Unix/Linux operating system family. Wine is a mature project involving almost 17 years of work to get Windows applications to run on Unix and Linux systems.
Actually, you don’t need CrossOver Linux to run Windows applications on Linux. You can do it with Wine alone — if you know exactly what you’re doing. What CrossOver brings to the table is automated installation of Windows applications, and technical support. And in this latest version, the CrossOver interface has been improved so it’s easier than ever to install and manage Windows applications.
